What are Different Types of Computer

Computers can be divided into the following 3 types on the basis of their working mechanism:

1) Analog Computers

2) Digital Computers

3) Hybrid Computers

1. Analog Computers

Analog computer is used to measure continuous values. It measures a physical property like voltage, pressure, speed, time and temperature. An analog computer takes input in analog form and gives output in analog form.
Its output is usually displayed on a meter or scale. Analog computer has low memory and fewer functions. Analog computer is mainly used in the field of engineering and medicine. Examples include:

Examples of Analog Computers include:

examples of analog computer speedo meter

1. Thermometer
2. Speedometer
3. Analog clock

2. Digital Computers

A digital computer works with digital data. Digital computer uses binary number system. Binary number system consists of only two digits 0 and 1. A digital computer represents data in digital signals. A 0 represents OFF and a 1 represents ON. Digital computer performs arithmetic and logical operations on data. It gives output in digital form.
Digital computers are very fast. These computers can store results. They have large Memory(that is data storing capacity). Today most of the computers used in offices and homes are Digital computers.
Examples:

examples of digital computer personal computer

1. Personal Computer-(also called PC or Micro Computer)
2. Digital Score board
3. Digital watch

3. Hybrid Computers

A hybrid computer is a combination of both analog and digital computer. Hybrid ccomputer can handle both analog and digital data. A hybrid computer combines the best characteristics of both the analog and digital computer. It can accept data in both analog and digital form.
Examples:

1. Hybrid computer devices are used in hospitals that may calculate patient's heart function, temperature and blood pressure etc. This calculation may be converted into numbers and shown in digital form. For example,

The Vital Signs Monitoring unit

also called VSM in short. It has Blood Pressure monitor, ECG monitor, respiratory monitor, and is also used for monitoring anesthesia.
2. Hybrid computers are also used in spaceships and missile system.
3. Hybrid Computer Machines are generally used in scientific applications
4. Hybrid computers are used for controlling industrial processes.

Explain different types of storage devices

Topic: Explain different types of storage devices in Computer systems Storage Devices Storage devices are used to store data and instructions permanently. Storage devices are also called secondary storage devices / backing storage devices / external storage devices or auxiliary storage devices. Examples of storage devices include Hard Disk, CD and DVD etc. Why Secondary Storage Devices are Used? Secondary storage devices are used because: Primary memory(RAM) is volatile and temporary. When computer is switched off, all data in ram is erased. Storage devices can store large amounts of data and instructions permanently whereas Primary memory has less capacity of storing data. Types Of Storage Devices There are three main types of storage devices: Magnetic Tape Magnetic Disk Optical Disk Flash Memory storage devices 1. Magnetic Tape Magnetic tape is the oldest storage device. It is made of plastic coated with m...

Explain Different Types Of Output Devices

Output devices Out put devices are used to display results of processing to the user. They perform the following functions: Receive results from memory Convert data into human readable form Display results to the user Examples include: Monitor, printer, plotter, speaker, and multimedia projector. Different Types of Output Devices 1. Monitor LCD Monitor CTR Monitor Monitor is the most commonly used output device used to display results of processing. It has a TV like shape. Pictures on monitor are formed with picture elements called PIXEL. Monitors may be Monochrome that will display results in Black & White. Color Monitors are also available. They display results in multi colors. Monitor produces soft copy output. 2. Printers Printers are used to produce hard copy out put. They print processing results on paper. Printers are divided into two main categories: · ...

Types Of Scanners Input Device

Scanner / Optical Scanner A scanner is an input device for computer. It can scan any printed document with text as well as images. It will : Read any printed paper or picture, Convert text or images into digital form Saves this converted digital file into computer storage for later use Uses Of Optical Scanners You can scan your documents or pictures to: Store into computer memory. To save lot of effort and time because if you type the whole text on printed page, it will take effort as well as time). Show image or text on computer screen or on a multimedia projector's screen. In addition, you can send this scanned document or image to your friends all over the world with the help of Internet & Email. You can publish the scanned documents or images on your website or blog. You can apply online and send the scanned images of your academic documents in any part of the world within minutes. If your scanner supports OCR - Optical Character Recognition, you can scan a page...
